also be able to refer you to classes, clinics or books on bicycle use,

service, repair or maintenance.

Cervélo Owner’s Manual

GENERAL WARNING:

Like any sport, bicycling involves risk of injury and damage. By

choosing to ride a bicycle, you assume the responsibility for that

risk, so you need to know — and to practice — the rules of safe and

responsible riding and of proper use and maintenance. Proper use

and maintenance of your bicycle reduces risk of injury.

This Manual contains many “Warnings” and “Cautions” concerning

the consequences of failure to maintain or inspect your bicycle and

of failure to follow safe cycling practices.

• The combination of the safety alert symbol and the word WARNING

indicates a potentially hazardous situation which, if not avoided, could

result in serious injury or death.

• The combination of the safety alert symbol and the word CAUTION

indicates a potentially hazardous situation which, if not avoided, may

result in minor or moderate injury, or is an alert against unsafe practices.

• The word CAUTION used without the safety alert symbol indicates

a situation which, if not avoided, could result in serious damage to

the bicycle or the voiding of your warranty.

Many of the Warnings and Cautions say “you may lose control and

fall”. Because any fall can result in serious injury or even death, we

do not always repeat the warning of possible injury or death.

Because it is impossible to anticipate every situation or condition

which can occur while riding, this Manual makes no representation

about the safe use of the bicycle under all conditions. There are risks

associated with the use of any bicycle which cannot be predicted or

avoided, and which are the sole responsibility of the rider.

A special note for parents:

As a parent or guardian, you are responsible for the activities and

safety of your minor child, and that includes making sure that the

bicycle is properly fitted to the child; that it is in good repair and

safe operating condition; that you and your child have learned and

understand the safe operation of the bicycle; and that you and your

child have learned, understand and obey not only the applicable

local motor vehicle, bicycle and traffic laws, but also the common

sense rules of safe and responsible bicycling. As a parent, you should

read this manual, as well as review its warnings and the bicycle’s functions

and operating procedures with your child, before letting your child ride

the bicycle.

WARNING: Make sure that your child always wears an approved

bicycle helmet when riding; but also make sure that your child

understands that a bicycle helmet is for bicycling only, and must

be removed when not riding. A helmet must not be worn while

playing, in play areas, on playground equipment, while climbing

trees, or at any time while not riding a bicycle. Failure to follow

this warning could result in serious injury or death.

Cervélo Owner’s Manual

1. FIRST

NOTE: We strongly urge you to read this Manual in its entirety before

your first ride. At the very least, read and make sure that you understand

each point in this section, and refer to the cited sections on any issue

which you don’t completely understand. Please note that not all bicycles

have all of the features described in this Manual. Ask your dealer to point

out the features of your bicycle.

A. Bike Fit

1. Is your bike the right size? To check, see Section 3.A. If your bicycle is

too large or too small for you, you may lose control and fall. If your

new bike is not the right size, ask your dealer to exchange it before

you ride it.

2. Is the saddle at the right height? To check, see Section 3.B. If you

adjust your saddle height, follow the Minimum Insertion instructions

in Section 3.B.

3. Are saddle and seatpost securely clamped? A correctly tightened

saddle will allow no saddle movement in any direction. See Section 3.B.

4. Are the stem and handlebars at the right height for you? If not, see

Section 3.C.

5. Can you comfortably operate the brakes? If not, you may be able

to adjust their angle and reach. See Section 3.D and 3.E.

6. Do you fully understand how to operate your new bicycle? If not,

before your first ride, have your dealer explain any functions or

features which you do not understand.

B. Safety First

1. Always wear an approved helmet when riding

your bike, and follow the helmet manufacturer’s

instructions for fit, use and care. (fig. 1)

2. Do you have all the other required and

recommendedsafety equipment? (See Section 2).

It’s your responsibility to familiarize yourself with

the laws of the areas where you ride, and to comply

with all applicable laws.

3. Do you know how to correctly operate your wheel quick releases?

Check Section 4.B.1 to make sure. Riding with an improperly

adjusted wheel quick release can cause the wheel to wobble or

disengage from the bicycle, and cause serious injury or death.

4. If your bike has toeclips and straps or clipless (“step-in”) pedals,

make sure you know how they work (see Section 4.E). These

pedals require special techniques and skills. Follow the pedal

manufacturer’s instructions for use, adjustment and care.

5. Do you have “toe overlap”? On smaller framed bicycles your toe

or toeclip may be able to contact the front wheel when a pedal is

all the way forward and the wheel is turned. Read Section 4.E. to

check whether you have toeclip overlap.

fig. 1

Cervélo Owner’s Manual

C. Mechanical Safety Check

Routinely check the condition of your bicycle before every ride.

Nuts, bolts screws & other fasteners: Because manufacturers use a

wide variety of fastener sizes and shapes made in a variety of materials,

often differing by model and component, it is not possible for this

Manual to specify correct torque (tightening force) for each specific

fastener on your bicycle. We can tell you the importance of correct

torque, but not the specific torque required for each fastener on your

bicycle (see Section 4. G). To correctly torque a fastener, a torque wrench

must be used. A professional bicycle mechanic with a torque wrench

should torque the fasteners on your bicycle. If you choose to work on

your own bicycle you must get correct tightening torque specifications

from the bicycle or component manufacturer or from your dealer. If

you need to make an adjustment at home or in the field, we urge you

to exercise care, and to have the fasteners you worked on checked by

your dealer as soon as possible.

WARNING: Correct tightening force on fasteners – nuts, bolts,

screws – on your bicycle is important. Too little force, and the

fastener may not hold securely. Too much force, and the

fastener can strip threads, stretch, deform or break. Either

way, incorrect tightening force can result in component

failure, which can cause you to loose control and fall.

Make sure nothing is loose. Lift the front wheel off the ground by two

or three inches, then let it bounce on the ground. Anything sound,

feel or look loose? Do a visual and tactile inspection of the whole bike.

Any loose parts or accessories? If so, secure them. If you’re not sure,

ask someone with experience to check.

Tires & Wheels: Make sure tires are correctly inflated (see Section 4.F.1).

Check by putting one hand on the saddle, one on the intersection of

the handlebars and stem, then bouncing your weight on the bike while

looking at tire deflection. Compare what you see with how it looks

when you know the tires are correctly inflated; and adjust if necessary.

Are both tires in good shape? Spin each wheel slowly and look for

cuts in the tread and sidewall. Replace damaged tires before riding

the bike.

Are both wheels true? Spin each wheel and check for brake clearance

and side-to-side wobble. If a wheel wobbles side to side even slightly,

or rubs against or hits the brake pads, take the bike to a qualified bike

shop to have the wheel trued.

CAUTION: Wheels must be true for the brakes to work effectively.

Wheel truing is a skill which requires special tools and experience.

Do not attempt to true a wheel unless you have the knowledge,

experience and tools needed to do the job correctly.

Are both wheel rims clean and undamaged? Make sure the rims are

clean and undamaged along the braking surface, and check for excess

rim wear. See Section 5.A.4.

Brakes: Check the brakes for proper operation (see Sections 4.C).

Squeeze the brake levers. Are the brake quick-releases closed?

All control cables/hoses are seated and securely engaged? Do

the brake pads contact the wheel rim squarely and make full contact

with the rim? Do the brake pads touch the wheel rim within an inch

of brake lever movement? Can you apply full braking force at the

levers without having them touch the handlebar? If not, your brakes

Cervélo Owner’s Manual

need adjustment. Do not ride the bike until the brakes are properly

adjusted by a professional bicycle mechanic.

Quick Releases: Make sure the front wheel, rear wheel and seat post

quick releases are properly adjusted and in the locked position. See

Section 4.B.

Handlebar and saddle alignment: Make sure the saddle and

handlebar stem are parallel to the bike’s center line and clamped tight

enough so that you can’t twist them out of alignment. See Sections 3.B

and 3.C.

Handlebar ends: Make sure the handlebar grips are secure and in

good condition. If not, have your dealer replace them. Make sure

the handlebar ends and aerobar extensions are plugged. If not,

have your dealer plug them before you ride. If the handlebars have

aerobar extensions, make sure they are clamped tight enough so

you can’t twist them.

WARNING: Loose or damaged handlebar grips or aerobar

extensions can cause you to lose control and fall. Unplugged

handlebars or extensions can cut you and cause serious injury

in an otherwise minor accident.

Rear derailleur hanger: Make sure the rear derailleur hanger is

straight and undamaged. If bent or broken, have your dealer replace it

before you ride. See Section 5.B.

VERY IMPORTANT SAFETY NOTE: Please also read and become

thoroughly familiar with the important information on the

lifespan of your bicycle and its components in Appendix A.

D. Intended Use

Cervélo produces bicycles designed and built for road racing, time

trailing and triathlon. They are intended to be used for long, fast types of

rides on smooth surfaces such as paved roads, and are not designed for

use on rough or loose, off-road surfaces. Small changes to components

such as wheels or tires will not render the bicycle suitable for use in such

harsh conditions. Please consult your Cervélo dealer to ensure you are

properly equipped to meet your unique requirements & specific goals.

E. First Ride

When you buckle on your helmet and go for your first familiarization

ride on your new bicycle, be sure to pick a controlled environment, away

from cars, other cyclists, obstacles or other hazards. Ride to become

familiar with the controls, features and performance of your new bike.

Familiarize yourself with the braking action of the bike (see Section 4.C).

Test the brakes at slow speed, putting your weight toward the rear and

and gently applying the brakes, rear brake first. Sudden or excessive

application of the front brake could pitch you over the handlebars.

Applying brakes too hard can lock up a wheel, which could cause you to

lose control and fall. Skidding is an example of what can happen when a

wheel locks up.

If your bicycle has toeclips or clipless pedals, practice getting in and

out of the pedals. See paragraph B.4 above and Section 4.E.4.

Practice shifting the gears (see Section 4.D). Remember to never move

the shifter while pedaling backward, nor pedal backwards immediately

after having moved the shifter. This could jam the chain and cause

serious damage to the bicycle.

Cervélo Owner’s Manual

Check out the handling and response of the bike; and check the comfort.

If you have any questions, or if you feel anything about the bike

is not as it should be, consult your dealer before your next ride.

2. SAFETY

A. The Basics

WARNING: Many countries require specific safety devices. It is

your responsibility to familiarize yourself with the laws of the

region where you ride and to comply with all applicable laws,

including properly equipping yourself and your bike as the

law requires.

Observe all local bicycle laws and regulations. Observe

regulations about bicycle lighting, reflectors, licensing of

bicycles, riding on sidewalks, laws regulating bike path and

trail use, helmet laws, child carrier laws, and special bicycle

traffic laws. It’s your responsibility to know and obey the laws.

1. Always wear a cycling helmet which meets the latest certification

standards and is appropriate for the type of riding you do. Always

follow the helmet manufacturer’s instructions for fit, use and care of

your helmet. Most serious bicycle injuries involve head injuries which

might have been avoided if the rider had worn an appropriate helmet.

WARNING: Failure to wear a helmet when riding may result in

serious injury or death.

2. Always do the Mechanical Safety Check (Section 1.C) before you

get on a bike.

3. Be thoroughly familiar with the controls of your bicycle: brakes

(Section 4.C.); pedals (Section 4.E.); shifting (Section 4.D.)

4. Be careful to keep body parts and other objects away from the

sharp teeth of chainrings, the moving chain, the turning pedals

and cranks, and the spinning wheels of your bicycle.

5. Always wear:

• Shoes that will stay on your feet and will grip the pedals. Make sure

that shoe laces cannot get into moving parts, and never ride barefoot

or in sandals.

• Bright, visible clothing that is not so loose that it can be tangled in the

bicycle or snagged by objects at the side of the road or trail.

• Protective eyewear, to protect against airborne dirt, dust and bugs

— tinted when the sun is bright, clear when it’s not.

6. Don’t jump with your bike. Jumping a bike can be fun; but it can

put huge and unpredictable stress on the bicycle and its components.

Riders who insist on jumping their bikes risk serious damage, to their

bicycles as well as to themselves. Before you attempt to jump or race

with your bike, read and understand Section 2.E.

7. Ride at a speed appropriate for current conditions and surroundings.

Increased speed means higher risk.

B. Riding Safety

1. You are sharing the road or the path with others — motorists,

pedestrians and other cyclists. Respect their rights.

2. Ride defensively. Always assume that others do not see you.

Cervélo Owner’s Manual

3. Look ahead, and be ready to avoid:

• Vehicles slowing or turning, entering the road or your lane ahead

of you, or coming up behind you.

• Parked car doors opening.

• Pedestrians stepping out.

• Children or pets playing near the road.

• Pot holes, sewer grating, railroad tracks, expansion joints, road or

sidewalk construction, debris and other obstructions that could

cause you to swerve into traffic, catch your wheel or cause you to

have an accident.

• The many other hazards and distractions which can occur on a

bicycle ride.

4. Ride in designated bike lanes, on designated bike paths or as close

to the edge of the road as possible, in the direction of traffic flow

or as directed by local governing laws.

5. Stop at stop signs and traffic lights; slow down and look both ways

at street intersections. Remember that a bicycle always loses in a

collision with a motor vehicle, so be prepared to yield even if you

have the right of way.

6. Use approved hand signals for turning and stopping.

7. Never ride with headphones. They mask traffic sounds and

emergency vehicle sirens, distract you from concentrating on

what’s going on around you, and their wires can tangle in the

moving parts of the bicycle, causing you to lose control.

8. Never carry a passenger, unless it is a small child wearing an approved

helmet and secured in a correctly mounted child carrier or a child-

carrying trailer.

9. Never carry anything which obstructs your vision or your complete

control of the bicycle, or which could become entangled in the

moving parts of the bicycle.

10. Never hitch a ride by holding on to another vehicle.

11. Don’t do stunts, wheelies or jumps. If you intend to do stunts, wheelies,

jumps or go racing with your bike despite our advice not to, read

Section 2.E, Competition, now. Think carefully about your skills before

deciding to take the large risks that go with this kind of riding.

12. Don’t weave through traffic or make any moves that may surprise

people with whom you are sharing the road.

13. Observe and yield the right of way.

14. Never ride your bicycle while under the influence of alcohol or drugs.

15. If possible, avoid riding in bad weather, when visibility is obscured,

at dawn, dusk or in the dark, or when extremely tired. Each of these

conditions increases the risk of accident.

16. Always take along some kind of identification, so that people know

who you are in case of an accident; and take along a couple of dollars

in cash for a candy bar, a cool drink or an emergency phone call.

Cervélo Owner’s Manual

C. Wet Weather Riding

WARNING: Wet weather impairs traction, braking and visibility,

both for the bicyclist and for other vehicles sharing the road.

The risk of an accident is dramatically increased in wet conditions.

Under wet conditions, the stopping power of your brakes (as well as the

brakes of other vehicles sharing the road) is dramatically reduced and

your tires don’t grip nearly as well. This makes it harder to control speed

and easier to lose control. To make sure that you can slow down and

stop safely in wet conditions, ride more slowly and apply your brakes

earlier and more gradually than you would under normal, dry conditions.

See also Section 4.C.

D. Night Riding

Riding a bicycle at night is many times more dangerous than riding during

the day. A bicyclist is very difficult for motorists and pedestrians to see.

Therefore, children should never ride at dawn, at dusk or at night. Adults

who chose to accept the greatly increased risk of riding at dawn, at dusk

or at night need to take extra care both riding and choosing specialized

equipment which helps reduce that risk. Consult your dealer about night

riding safety equipment.

WARNING: Reflectors are not a substitute for required lights.

Riding at dawn, at dusk, at night or at other times of poor visibility

without an adequate bicycle lighting system is dangerous and

may result in serious injury or death.

Bicycle reflectors are designed to pick up and reflect car lights and

street lights in a way that may help you to be seen and recognized as a

moving bicyclist.

CAUTION: Check reflectors and their mounting brackets

regularly to make sure that they are clean, straight, unbroken

and securely mounted. Have your dealer replace damaged

reflectors and straighten or tighten any that are bent or loose.

WARNING: Do not remove the installed front or rear reflectors

or reflector brackets from your bicycle. They are an integral part

of the bicycle’s safety system.

Removing the reflectors may reduce your visibility to others

using the roadway. Being struck by other vehicles may result

in serious injury or death.

If you choose to ride under conditions of poor visibility, check and

be sure you comply with all local laws about night riding, and take

the following strongly recommended additional precautions:

• Purchase and install battery or generator powered head and

tail lights which meet all regulatory requirements and provide

adequate visibility.

• Wear light colored, reflective clothing and accessories, such as a

reflective vest, reflective arm and leg bands, reflective stripes on

your helmet, flashing lights attached to your body and/or your

bicycle...any reflective device or light source that moves will help

you get the attention of approaching motorists, pedestrians and

other traffic.

• Make sure your clothing or anything you may be carrying on the

bicycle does not obstruct a reflector or light.

• Make sure that your bicycle is equipped with correctly positioned

and securely mounted reflectors.

Cervélo Owner’s Manual

While riding at dawn, at dusk or at night:

• Ride slowly.

• Avoid dark areas and areas of heavy or fast-moving traffic.

• Avoid road hazards.

• If possible, ride on familiar routes.

If riding in traffic:

• Be predictable. Ride so that drivers can see you and predict

your movements.

• Be alert. Ride defensively and expect the unexpected.

• If you plan to ride in traffic often, ask your dealer about traffic

safety classes or a good book on bicycle traffic safety.

E. Competition

By engaging in racing or aggressive riding you voluntarily assume an

increased risk of injury or death.

Not all bicycles are designed for these types of riding, and those that

are may not be suitable for all types of aggressive riding. Check with

your dealer or the bicycle’s manufacturer about the suitability of your

bicycle before engaging in competition.

When riding fast down hill, you can reach speeds seen on motorcycles,

and therefore face similar hazards and risks. Have your bicycle and

equipment carefully inspected by a qualified mechanic and be sure it is

in perfect condition. Take your bicycle to your dealer if anything breaks

or bends. Do not ride your bicycle when any part is damaged. Consult

with expert riders and race officials on conditions and equipment

advisable at the site where you plan to ride. Wear appropriate safety

gear. Ultimately, it is your responsibility to have proper equipment

and to be familiar with course conditions.

WARNING: Although many catalogs, advertisements and

articles about bicycling depict riders engaged in various

forms of racing, this activity can be extremely dangerous,

increases your risk of injury or death, and increases the

severity of any injury. Remember that the action depicted

is being performed by professionals with many years of

training and experience. Know your limits and always

wear a helmet and other appropriate safety gear. Even

with state-of-the-art protective safety gear, you could be

seriously injured or killed when riding downhill at speed or

in competition.

CAUTION: Bicycles and bicycle parts have limitations with

regard to strength and integrity, and this type of riding can

increase the likelihood of exceeding those limitations.

F. Aerobars

Caution should be exercised when utilizing aerobars at all times, as

these bars, while highly effective at decreasing aerodynamic drag,

also decrease the bicycle’s ability to steer and brake relative to standard

handlebars.

Braking is made more difficult when using aerobars as your hands

are positioned further from the brake levers compared to standard

handlebars – in an emergency you need first sit up and move your

hands back towards the base bar and out to the brake levers to begin

braking. If brake levers are attached to the aerobars, you must

Cervélo Owner’s Manual

remember that your weight is positioned further forward than

normal, with more weight on the front wheel. Caution should be

exercised when braking from this position as the forward weight

bias makes it more likely for you to flip over the front wheel if the

front brake is applied too strongly.

Regarding handling, the bike is more difficult to steer from the aero

hand position as you are steering with your elbows instead of hands,

and with a narrower total width as compared to standard handlebars.

This makes it more difficult to ride in a straight line, and the bike will

react more strongly to bumps or other unexpected inputs. It is highly

recommended that you initially practice riding in a smooth, flat area,

away from traffic, until you become familiar with the handling

characteristics imparted by aerobars. Once mastered, aerobars are

never recommended for use when riding in a group or in heavy

traffic for safety reasons.

WARNING: Failure to confirm compatibility, properly install,

operate and maintain any aerobar or related component or

accessory can result in serious injury or death.

G. Changing Components or Adding Accessories

There are many components and accessories available to enhance the

comfort, performance and appearance of your bicycle. However, if you

change components or add accessories, you do so at your own risk. The

bicycle’s manufacturer may not have tested that component or accessory

for compatibility, reliability or safety on your bicycle. Before installing any

component or accessory, including a different size tire, make sure that it

is compatible with your bicycle by checking with your dealer. Be sure to

read, understand and follow the instructions that accompany the products

you purchase for your bicycle. See also Appendix A, pp. 29.

WARNING: Failure to confirm compatibility, properly install,

operate and maintain any component or accessory can result

in serious injury or death.

CAUTION: Changing the components on your bike may void the

warranty. Refer to your warranty, and check with your dealer

before changing the components on your bike.

H. Maximum Weight

Cervélo frames have been designed and tested to withstand very high

loads, and as a result we have not traditionally assigned maximum

weight restrictions for our frames. However, your bicycle is also made up

of numerous individual components, all of which have their own unique

weight limits. As a result, Cervélo recommends that you consult your

dealer to ensure that all components selected for use on your bicycle

are suitable and safe for your intended use.

3. FIT

NOTE: Correct fit is an essential element of bicycling safety,

performance and comfort. Making the adjustments to your bicycle

which result in correct fit for your body and riding conditions requires

experience, skill and special tools. Always have your dealer make the

adjustments on your bicycle; or, if you have the experience, skill and

tools, have your dealer check your work before riding.

The fit suggestions below are based solely on safety concerns. They

specify the absolute minimum standards to ride the bike, but by no

means do they guarantee optimal performance. Much more elaborate

fit requirements are necessary to ensure optimal performance. For the

Cervélo Owner’s Manual

additional performance fitting requirements, please consult with

your dealer.

WARNING: If your bicycle does not fit properly, you may lose

control and fall. If your new bike doesn’t fit, ask your dealer

to exchange it before you ride it.

A. Standover Height

Standover height is the basic element of bike fit

(see fig. 2). It is the

distance from the ground to the top of the bicycle’s

frame at that point where your crotch is when

straddling the bike. To check for correct standover

height, straddle the bike while wearing the kind

of shoes in which you’ll be riding, and bounce

vigorously on your heels. If your crotch touches

the frame, the bike is too big for you. Don’t even ride the bike around

the block. A bike which you

ride only on paved surfaces and never take off-

road should give you a minimum standover height clearance of

two inches (5 cm). A bike that you’ll ride on unpaved surfaces should

give you a minimum of three inches (7.5 cm) of standover height

clearance. And a bike that you’ll use off road should give you four

inches (10 cm) or more of clearance.

WARNING: If you plan to use your bike for jumping or competition,

read Section 2.E again.

B. Saddle Position

Correct saddle adjustment is an important factor in getting the most

performance and comfort from your bicycle. If

the saddle position is not comfortable for you,

see your dealer.

The saddle can be adjusted in three directions:

1. Up and down adjustment. To check for correct

saddle height (fig. 3):

• sit on the saddle;

• place one heel on a pedal;

• rotate the crank until the pedal with your

heel on it is in the down position and the

crank arm is parallel to the seat tube.

If your leg is not completely straight, your saddle

height needs to be adjusted. If your hips must

rock for the heel to reach the pedal, the saddle is

too high. If your leg is bent at the knee with your heel on the pedal, the

saddle is too low.

Once the saddle is at the correct height, make sure that the seatpost

does not project from the frame beyond its “Minimum Insertion”

mark, which means that the minimum insertion mark should never

be visible above the frame once adjusted to your correct position

(fig. 4). If the “Minimum Insertion” mark is visible once your saddle is

properly adjusted, contact your dealer to have

the seatpost replaced with a longer one.

WARNING: If your seat post projects from the frame beyond

the Minimum Insertion or Maximum Extension mark (see fig.

fig. 2

fig. 3

Min. Insertio

Mark

fig. 4

Cervélo Owner’s Manual

4), the seat post may break, which could cause you to lose

control and fall.

Note that some seatposts also have a second insertion mark entitled

“Maximum Insertion”. If present on your bicycle, your seatpost should

never be lowered into the frame beyond the “Maximum Insertion” point,

meaning that this line must always be visible above the frame once the

saddle is properly adjusted. If the “Maximum Insertion” mark is no longer

visible once your saddle is properly adjusted, contact your dealer to have

the seatpost replaced with a shorter one.

WARNING: If your seat post is inserted into the frame beyond

the Maximum Insertion mark, the seat post may break, which

could cause you to lose control and fall.

Minimum saddle height is defined as the smallest possible distance

between the center of the bottom bracket and the top of the saddle

on a given bicycle. It can be measured along the plane of the seat tube

from the top of the saddle to the center of the crank axle. Several

factors can influence the minimum saddle height including thickness

of the saddle, design of the seatpost clamp, seatpost length, frame size,

and frame design. Cervélo does not specify the minimum saddle

height on our standard geometry tables due to the variability of

this dimension with component changes; instead we recommend

consulting your dealer to assist in determining appropriate sizing and

in fitting your bicycle to you.

2. Front and back adjustment. The saddle can be adjusted forward or

back to help you get the optimal position on the bike. Ask your dealer

to set the saddle for your optimal riding position and to show you

how to make this adjustment.

3. Saddle angle adjustment. Most people prefer a horizontal saddle; but

some riders like the saddle nose angled up or down just a little. Your

dealer can adjust saddle angle or teach you how to do it.

Small changes in saddle position can have a substantial effect on

performance and comfort. To find your best saddle position, make

only one adjustment at a time.

WARNING: After any saddle adjustment, be sure that the saddle

adjusting mechanism is properly tightened before riding.

A loose saddle clamp or seat post binder can cause damage

to the seat post, or can cause you to lose control and fall. A

correctly tightened saddle adjusting mechanism will allow no

saddle movement in any direction. Periodically check to make

sure that the saddle adjusting mechanism is properly tightened.

If, in spite of carefully adjusting the saddle height, tilt and fore-and-aft

position, your saddle is still uncomfortable, you may need a different

saddle design. Saddles, like people, come in many different shapes, sizes

and resilience. Your dealer can help you select a saddle which, when

correctly adjusted for your body and riding style, will be comfortable.

WARNING: Some people have claimed that extended riding with

a saddle which is incorrectly adjusted or which does not support

your pelvic area correctly can cause short-term or long-term

injury to nerves and blood vessels, or even impotence. If your

saddle causes you pain, numbness or other discomfort, listen

to your body and stop riding until you see your dealer about

Cervélo Owner’s Manual

saddle adjustment or a different saddle.

C. Handlebar Height and Angle

Your bike is equipped with a “threadless” stem, which clamps on to

the outside of the steerer tube. Your dealer may be able to change

handlebar height by moving height adjustment spacers from below

the stem to above the stem, or vice versa. Otherwise, you’ll have to get

a stem of different length or rise. Consult your dealer. Do not attempt

to do this yourself, as it requires special knowledge.

Maximum Spacer Height

• All forks should be installed in accordance with the manufacturer’s

instructions.

WARNING: Exceeding the maximum spacer height can result in

damage to the fork’s steerer tube, which could cause you to lose

control and fall.

WARNING: On some bicycles, changing the stem or stem height

can affect the tension of the front brake cable, locking the

front brake or creating excess cable slack which can make the

front brake inoperable. If the front brake pads move in towards

the wheel rim or out away from the wheel rim when the stem

or stem height is changed, the brakes must be correctly adjusted

before you ride the bicycle.

WARNING: The top of the stem where fitted over the fork

steerer tube must not extend more than 5 mm above the top

of the steerer. If the stem is extended beyond this height the

stem may break or damage the fork’s steerer tube, which could

cause you to lose control and fall.

Your dealer may also be able to change the angle of the handlebar

or aerobar extensions.

WARNING: An insufficiently tightened stem binder bolt,

handlebar binder bolt or aerobar extension clamping bolt

may compromise steering action, which could cause you

to lose control and fall. Place the front wheel of the bicycle

between your legs and attempt to twist the handlebar/

stem assembly. If you can twist the stem in relation to the

front wheel, turn the handlebars in relation to the stem, or

turn the aerobar extensions in relation to the handlebar,

the bolts are insufficiently tightened.

D. Control Position Adjustments

The angle of the brake and shift control levers and their position on the

handlebars can be changed. Ask your dealer to make the adjustments

for you.

E. Brake Reach

Many bikes have brake levers which can be adjusted for reach. If you

have small hands or find it difficult to squeeze the brake levers, your

dealer can either adjust the reach or fit shorter reach brake levers.

WARNING: The shorter the brake lever reach, the more critical it

is to have correctly adjusted brakes, so that full braking power

can be applied within available brake lever travel. Brake lever

travel insufficient to apply full braking power can result in loss

of control, which may result in serious injury or death.

4. TECHNICAL

It’s important to your safety, performance and enjoyment to understand

how things work on your bicycle. We urge you to ask your dealer how to

do the things described in this section before you attempt them yourself,

and that you have your dealer check your work before you ride the bike.

If you have even the slightest doubt as to whether you understand

something in this section of the Manual, talk to your dealer. See also

Appendix A, pp. 29.

A. Initial Assembly

Cervélo bicycles are shipped from the factory to the dealer only partially

assembled. Your dealer will complete the assembly of the bicycle, and

perform any adjustments required to make it fit you. It is strongly recom-

mended that you allow your dealer to perform the assembly and fitting

operations, as it requires specific knowledge of each part, appropriate

tools, and understanding of the interactions of various materials. Your

bicycle is a high performance machine, much like a racing car, and as such

requires skilled maintenance in order to function safely and effectively.

Your dealer will perform the following assembly operations before

your bicycle is delivered to you:

1. Fork cut to appropriate length.

2. Headset & stem installed and adjusted.

3. Handlebars clamped into stem.

4. Brake/shift levers installed onto handlebars.

5. Front brake installed on fork.

6. Brake and shifter cables threaded & attached.

7. Brakes and derailleurs adjusted.

8. Handlebars wrapped with bar tape & plugged.

9. Seat and seatpost installed.

10. Wheels installed.

11. Pedals (of your choice) installed.

If you choose to perform any assembly operations yourself, ensure

that all operations are done in accordance with the specific assembly

instructions published by the component manufacturer. These

assembly instructions are included in the bike box provided to your

dealer. Alternatively, assembly instructions are usually posted on

the component manufacturer’s websites, or are available from their

service departments. Links to commonly-referenced component

assembly instructions (by brand) are provided below. Please

ensure that you locate and follow the directions for your particular

component model.

B. Wheels

1. Wheel Quick Release

WARNING: Riding with an improperly adjusted wheel quick

release can allow the wheel to wobble or fall off the bicycle,

Cervélo Owner’s Manual

which can cause serious injury or death. Therefore, it is

essential that you:

1. Ask your dealer to help you make sure you know

how to install and remove your wheels safely.

2. Understand and apply the correct technique for

clamping your wheel in place with a quick release.

3. Each time, before you ride the bike, check that the

wheel is securely clamped.

The wheel quick release uses a cam action to clamp the bike’s wheel

in place (see fig. 5). Because of its adjustable nature, it is critical that

you understand how it works, how to use it properly, and how much

force you need to apply to secure the wheel.

WARNING: The full force of the cam action is needed

to clamp the wheel securely. Holding the nut with one hand

and turning the lever like a wing nut with the other hand

until everything is as tight as you can get it will not clamp

the wheel safely in the dropouts.

a. Adjusting the Quick Release Mechanism

The wheel hub is clamped in place by the force of the quick release

cam pushing against one dropout and pulling the tension adjusting

nut, by way of the skewer, against the other dropout. The amount

of clamping force is controlled by the tension adjusting nut. Turning

the tension adjusting nut clockwise while keeping the cam lever

from rotating increases clamping force; turning it counterclockwise

while keeping the cam lever from rotating reduces clamping force.

Less than half a turn of the tension adjusting nut can make the

difference between safe clamping force and unsafe clamping force.

b. Front Wheel Secondary Retention Devices

Most bicycles have front forks which utilize a secondary wheel retention

device to reduce the risk of the wheel disengaging from the fork if the

quick release is incorrectly adjusted. Secondary retention devices are not

a substitute for correct quick release adjustment.

Secondary retention devices fall into two basic categories:

(1) The clip-on type is a part which the manufacturer adds to the

front wheel hub or front fork.

(2) The integral type is molded, cast or machined into the outer

faces of the front fork dropouts.

Ask your dealer to explain the particular secondary retention

device on your bike.

WARNING: Do not remove or disable the secondary retention

Cervélo Owner’s Manual

device. As its name implies, it serves as a

back-up for a critical adjustment. If the quick

release is not adjusted correctly, the

secondary retention device can reduce the

risk of the wheel

disengaging from the fork. Removing or

disabling the secon-

dary retention device may also void the

warranty.

Secondary retention devices are not a substitute for correct

quick release adjustment. Failure to properly adjust the

quick release mechanism can cause the wheel to wobble or

disengage, disengage, which could cause you to loose control

and fall, resulting in serious injury or death.

2. Removing and Installing Quick Release Wheels

a. Removing a Quick Release Front Wheel

(1) If your bike has rim brakes, disengage the brake’s quick-release

mechanism to increase the clearance between the tire and the

brake pads (See Section 4.C fig. 8 and 9).

(2) Move the wheel’s quick-release lever from the locked or CLOSED

position to the OPEN position (fig. 6). Quick release levers should

be embossed with the words “OPEN” and “CLOSED” to indicate

the current position of the lever.

(3) If your front fork does not have a secondary retention device go

to step (5).

(4) If your front fork has a clip-on type secondary retention device,

disengage it and go to step (5). If your front fork has an integral

secondary retention device, loosen the tension adjusting nut

enough to allow removing the wheel; then go to the next step.

(5) Raise the front wheel a few inches off the ground and tap the

top of the wheel with the palm of your hand to release the

wheel from the front fork.

b. Installing a Quick Release Front Wheel

(1) Move the quick-release lever so that it curves away from the

wheel (fig. 6). This is the OPEN position.

(2) With the steering fork facing forward, insert the wheel between

the fork blades so that the axle seats firmly at the top of the slots

which are at the tips of the fork blades — the fork dropouts. The

quick-release lever should be on the left side of the bicycle. If your

bike has a clip-on type secondary retention device, engage it.

(3) Holding the quick-release lever in the OPEN position with your

right hand, tighten the tension adjusting nut with your left hand

until it is finger tight against the fork dropout (fig. 6).

(4) While pushing the wheel firmly to the top of the slots in the fork

dropouts, and at the same time centering the wheel rim in the fork,

move the quick-release lever upwards and swing it into the CLOSED

position (fig. 5). The lever should now be parallel to the fork blade

and curved toward the wheel. To apply enough clamping force, you

should have to wrap your fingers around the fork blade for leverage,

and the lever should leave a clear imprint in the palm of your hand.

WARNING: Securely clamping the wheel takes considerable

until it comes out of the rear dropouts.

d. Installing a Quick Release Rear Wheel

(1) Make sure that the rear derailleur is still in its outermost, high

gear, position

(2) Pull the derailleur body back with your right hand.

(3) Move the quick-release lever to the OPEN position (see fig. 6).

The lever should be on the side of the wheel opposite the

derailleur and freewheel sprockets.

(4) Put the chain on top of the smallest freewheel sprocket. Then,

insert the wheel up and back into the frame dropouts and pull

it all the way in to the dropouts.

(5) Tighten the quick-release adjusting nut until it is finger tight

against the frame dropout; then swing the lever toward the front

of the bike until it is parallel to the frame’s chainstay or seatstay and

is curved toward the wheel (fig. 7). To apply enough clamping

force, you should have to wrap your fingers around a frame tube

for leverage, and the lever should leave a clear imprint in the palm of

your hand.

WARNING: Securely clamping the wheel takes considerable

force. If you can fully close the quick release without wrapping

your fingers around the seatstay or chainstay for leverage, and

the lever does not leave a clear imprint in the palm of your

hand, the tension is insufficient. Open the lever; turn the

tension adjusting nut clockwise a quarter turn; then try again.

force. If you can fully close the quick release without wrapping

your fingers around the fork blade for leverage, and the lever

does not leave a clear imprint in the palm of your hand, the

tension is insufficient. Open the lever; turn the tension adjusting

nut clockwise a quarter turn; then try again.

(5) If the lever cannot be pushed all the way to a position parallel to the

fork blade, return the lever to the OPEN position. Then turn the tension

adjusting nut counterclockwise one-quarter turn and try tightening

the lever again.

(6) Re-engage the brake quick-release mechanism to restore correct

brake pad-to-rim clearance; spin the wheel to make sure that it is

centered in the frame and clears the brake pads; then squeeze the

brake lever and make sure that the brakes are operating correctly.

c. Removing a Quick Release Rear Wheel

(1) Shift the rear derailleur to high gear (the smallest, outermost

rear sprocket).

(2) If your bike has rim brakes, disengage the

brake’s quick-release mechanism to increase

the clearance between the wheel rim

and the brake pads (see Section 4.C, fig. 8 and

9).

(3) Pull the derailleur body back with your right hand.

(4) Move the quick-release lever to the OPEN position (fig. 6).

(5) Lift the rear wheel off the ground a few inches and, with the

derailleur still pulled back, push the wheel forward and down
